title: Low temperature short-range ordering caused by Mn²(+) doping of Rb₃H(SO₄)₂.
abstract: The low temperature behaviour of Rb₃H(SO₄)₂ and Rb₃D(SO₄)₂ and their doped analogues was investigated by means of their dielectric response. Electron paramagnetic resonance was used to control the impurity concentration. Influence of different admixtures on ferroic properties is discussed. It has been shown that an appropriately chosen impurity in doped Rb₃H(SO₄)₂ can lead to a short-range ordering similar to that observed for doped incipient ferroelectric-like SrTiO₃ and KTaO₃.
